EARTH-AUSER.

SPECIFICATION forming part of Letters Patent No. 362,562, datedlVIay 10, 1887.

Application filed February 28, 1887. Serial No. 229,194.

To @ZZ whom, it Hwy/,concejala Beit known that I, JAMEs WELLS, a citizen of the United States of America, residing at' Paris, in the county of Bourbon and State of Kentucky, have invented a new and useful Earth-Auger, of which the following is a specification. Y

- My invention has relation to improvements in implements for boring into the soil, such as making post-holes and similar excavations; and the object -is to 'provide an implement'of the class named which may be readily and certainly adjusted to bore holes of different diameters and in which adjustment the'points of the blades may be set in proper cutting position notwithstanding the enlargement or reduction of the diameter of the bore the implement may be set to. l

With these objects in View my invention consists in the novel construction of parts and their combination, as will be hereinafter more fully described, and especially as will be specifically pointed out in the claim vmade hereto, as required by statute.

I have fully illustrated my improvements in the accompanying drawings, wherein- Figure l is a perspective View of the implement. Fig. 2 is a'view of thehandleand head with the adjustable plates, and Fig. 3 is aview of one of the blades with the head-piece fixed thereto.` 1

In the drawings similar parts are identified by like notations, and reference being thereto had, the letter A designates the stem of the auger provided with a handle or cross-bar, 1, fixed to its upper end, and formed with a rectangular head, 2, at its lower end, to receive the sliding plates carrying the angular plates, as hereinafter described, to which the blades are attached.

Theletter B designates sliding plates. These are of such length as to meet the size of the tool to which they may be applied, and, also, of such length that when arranged in position on the rectangular head the ends of the upper set shall set across the ends of the lower set, and thus keep them all in horizontal position and from turning on the fastening means. Each of these sliding plates is formed with a slot,

3, arranged .in the direction of its length,

and is adjustably heldto the head of the stem by setscre,ws, 4, projeetedthrough the vfor a larger bore.

said slots into the body of the head. These sliding plates are adjustable, as indicated, in horizontal direction, thereby affording means for setting the blades to any desired cut.

Theletter C designates angular plates. These are formed with the part 5 to set against the face of the sliding plates, and are secured thereto by set-screws 6. The other and outer arm of t-hese angular plates is struck at right angles to the part attached tothe sliding plates, and has its outer face formed to fit the inner face of the upper end of the cutting-blades. As will be seen, the attachment of these angular plates to the sliding plates permits them to be turned on the set-screws, holding them to the sliding plates in a .vertical movement in the blades inward or outward.

The letter l) designates the cuttingeblades. These are formed with their upper ends to set against the outer and angular arms of the angular plates, and are secured thereto by means of bolts or screws 8. From the part held against the arm of the angular plate the blades are bent inward, so that the points of the number shall almost meet; and the outer faces of the blades are somewhat rounded, and the inner faces thereof inclined in cross-section in the direction ofthe movement and are brought to a cutting-edge, as shown in the drawings. The stem 0f the auger and the sliding plates and the angular plates are made of iron, and the cutting-blades of steel;

It will be perceived from the foregoing that by sliding the slidingplates on their set-screws and clamping them in the desired place, the diameter of t-he bore is fixed as wanted; and that this being determined, the blades may be turned on the set-screws of the angular plates in the parts secured to the sliding plates, and the points of the blades thus brought in proper contiguity at the center, notwithstanding the slides on the head of the handle may be set If the implement is to be adj usted from a greater to a less bore, the slides are adjusted, as heretofore stated, on the setscrewsto determine the diameter, and then the points of the blades are drawn outward and the set-screws of the angle-plates fastened.

What I claim as my invention, and desire to secure by Letters Patent, isN f Thehereindescribed improved earthauger,

y arc of a circle, and thus carry the points of the V ICO comprising the handle formed with a rectcured to the outer armsof the angular plates7 Io angular head, 2, at its lower end, the sliding as set forth.
